# Quantum attraction by exchange of particles

hi,
the standard (?) explanation for particle exchange to produce
repulsion and attraction is at:
http://math.ucr.edu/home/baez/physics/Quantum/virtual_particles.html

this seems to me to have two problems.

1.) in the case of repulsion beteen two electrons,
the direction has to be fine tuned to contrive that the
absorbing electron gets hit by the photon.
the probability of that happening is zero.
(the probability of a straight line eminating from a
point hitting some other random point in 3-d space is zero)

2.) asymetry in that one electron is an emitter and one
is an absorber.

3.) attraction requires quite a bit of hand waving for such a
fundamental response (and also still requires a special fine tuning)

each particle emits virtual photons in all directions
(i am thinking sin waves in this example)
two electrons intereract because everything cancels out except
for the wave between them

..|...|..
-(e)=(e)- net effect: (e)=(e)
..|...|..

the net affect is a photon exchanged between them and repulsion
aka the usual feynman diagram >-<

electron and a positive charge interact similary, but because
of opposite charge

..|...|..
-(e)0(p)- net effect: -(e)0(p)-
..|...|..

the interior photon cancels to zero
leaving a net attraction
net efect is a feynman diagram -< >-

its kind of like a casimir effect.

for charge/EM the photon is like cos(q*wt + phi)
with phi the angle of emmission.
looking along the x-axis
for two charges q1 and q2
to the left
left=cos(q1 wt + pi ) + cos(q2 wt + pi)
in the middle
middle=cos(q1 wt + 0) + cos(q2 wt + pi)
to the right
right=cos(q1 wt + 0) + cos(q2 wt + 0)

if(q1 == q2) {
then left=0; right=0;
and there is an exchange of
photons in the middle = repulsion}

if(q1 == -q2){
then left=-2cos(qwt);right=2cos(qwt);
middle=0;
=attraction
}

even more speculative, if you say the phase of the
photon is somehow a property of the spin , this could
also explain why gravity is always attractive

what do you think? crazy? already done?
i should go back to work?

i think i have a sign wrong in my math, but you get the idea (i hope)
